Quarkus - Supersonic Subatomic Java

Quarkus is a Cloud Native, Container First framework for writing Java applications. A Kubernetes Native Java stack tailored for GraalVM & OpenJDK HotSpot, crafted from the best of breed Java libraries and standards. Quarkus tailors your application for GraalVM and HotSpot. Amazingly fast boot time, incredibly low RSS memory (not just heap size!) offering near instant scale up and high density memory utilization in container orchestration platforms like Kubernetes. It allows developers to automatically generate Kubernetes resources including building and deploying container images without having to manually create YAML files.

Quarkus is based on a reactive core allowing your application to mix reactive and imperative components. It helps to compose asynchronous operations and complete the result when everything is done without blocking the I/O threads using Mutiny Reactive API.
